Technische Universität Berlin offers an open position:
Research Assistant - salary grade E13 TV-L Berliner Hochschulen - 1st qualification period (PhD candidate)
part-time employment may be possible
Faculty III - Institute of Materials Sciences and Technologies / Chair of Materials EngineeringReference number: III-661/17 (starting at the earliest possible / for 5 years / closing date for applications 29/12/17)
Working field: Our Team is dedicated to research and teaching in materials science. Our research comprises the development
of hierarchically structured materials and the characterisation of structure/mechanical-property relationships on different length-scales.
We focus on complex loading combinations, especially fatigue.
Specific topics are:
1. ”Water glass”: Processing, microstructural and mechanical characterisation of hierarchical, porous structures based on water glass, for bone reinforcing scaffolds. Freeze casting, microwave sintering and other methods shall be applied for processing. The microstructural investigations will comprise for example light and electron microscopy, Xray diffraction and tomography, fluorescence spectroscopy. Mechanical characterisation will be performed by micro-/nanoindentation and quasistatic bending/compression testing.
2. ”Endodontic composites”: Characterisation of the dynamic processes and stress states during setting of composites used in endodontic treatments to understand interfacial failures: Laser based speckle interferometry methods (ESPI, shearography) will be used for high-resolution measurements of displacement fields. The experimental work will be augmented by finite element analyses of the developing stress fields.
3. ”Cementum fatigue”: Characterisation of the fatigue behaviour of cementum lining the roots of teeth: Fatigue experiments will be performed on specimens prepared from the roots of teeth, in a customised micro-testing-machine and in a nanoindenter. Fatigue induced microstructural changes will be investigated by synchrotron X-ray diffraction, light and electron microscopy and tomography.
4. ”Mg-SiC nanocomposites”: In silico characterisation of the porosity development during pressing and sintering of Mg-SiC nanocomposites by finite element modelling. The results shall be validated by 2D and 3D microstructural investigations by light and scanning electron microscopy, and nanotomography.
As part of the research work, the department shall be represented on national and international conferences, and the results shall be published
in renowned journals. The researchers are further responsible for the used machines and equipment.
The department offers a variety of Bachelor and Master courses for materials science and engineering students, for example ”Materials Science”,
”Materials Selection”, ”Fatigue”, or ”Bioinspired Materials”. The successful candidates will independently supervise
lab-courses, advise students, and support the teaching administration and will be responsible for the commited and qualified supervision of Bachelor and
Master theses. The future team members shall further take part in public relation tasks within the department.
